This study used Jeju scoria to dye cotton fabric and measured its dyeability, colorfastness, antibacterial activity, deodorization efficiency, ultraviolet protection, and far-infrared emission. The cotton fabric was colored to yellowish red and optimal dyeing can be achieved at a temperature of $80^{\circ}C$ for a dyeing time of 120 minutes with a colorant concentration of 25%(o.w.b). The colorfastness to light, rubbing, perspiration, and washing was 8, 5, 5, and 4~5 ratings respectively, where the wash colorfastness remained after 15 wash cycles. The cotton fabric dyed with Jeju scoria demonstrated excellent antimicrobial activity to Staphylococcus aureus and high deodorization efficiency. Ultraviolet protection factor was as high as 50+. The Jeju scoria can be used as a new colorant for the natural dyeing of silk.

The extracts drawn out from Sophora japonica by methanol was concentrated. Using this concentrate the silk was dyed, 400% conc. of dyeing material, $80^{\circ}C$ temperature of dyeing, 30 min time of dyeing. The K/S value of silk fabric was the most efficient for the simmordanting method. On the other hand, the amount of absorbed mordant the Cu-mordant was largest mordants. The surface colors on the dyed fabric depended heavily upon mordants or mordanting methods. For all cases, the value of the dyed fabric was dark. for the mordanting, color difference was distinct when using the Fe-mordant. Lightfastness of the color fastness was best in Cu-mordant. The Fe-, Cu- mordant showed the greatest antimicrobial activity.

The purpose of this study was to investigate the colorfastness of cotton and silk fabric dyed with extract of Lotus leaf princeps. The experimental items were classified into mordanting treatments, fabric components and kind of mordants. The experimental test was done by laundering, abrasion(dry/wet), perspiration(acid/alkali) , light fastness, color difference by C.C.M(computer color matching) system and K/S test. The summarized findings resulting from the experiment and investigation are as follows: In the C.C.M and K/S test on mordanting method and kind of fabrics, co-mordanting treatment method and protein fabric (silk) were the most effective. Especially, Fe mordanting treatment was higher than Al, Cu, Cr and none-mordanting. In colorfastness on the mordants, perspiration and laundering fastness showed high grade (4-5) but grades of perspiration(2-3/4) and light fastness(1-3) were low.

To study the dyeability(ΔE value) and color depth of silk fabrics dyed with Impatiens balsamina extracts. its flower, leaf and stem was extracted by water. This paper investigated some experiments under the various dyeing conditions such as dyeing temperature, dyeing time, repetition of dyeing, dyeing pH with silk fabrics dyed with Impatiens balsamina extracts. The results obtained were as follows 1. It was found that $\lambda_{max}$ of silk fabrics dyed with Impatiens balsamina extract was 260nm and its flower, leaf , stem and different colored flower(white, pint violet) had same $\lambda_{max}$ at 260nm. 2. $\Delta{E}$ values were increased when dyeing temperature, repetition of dyeing and time was higher, value of munsell of silk fabrics dyed with Impatiens balsamina extract was Yellow-Red. But dyeing temperature, repetition of dyeing and time was higher, shifted to longer wavelenth side. 3. Silk fabric dyed with Impatiens balsamina extracts at acidic pH was colored reddish Yellow-Red, alkali bath colored yellowish Yellow-Red in silk fabrics dyed with Impatiens balsamina extract.

Recently, natural fiber reinforced composite is attracting attention and considered as an environmentally friendly material. Usually cellulosic fibers are used to reinforce the composites, but some protein fibers such as silk and wool serve the same purpose. In this paper, we proposed a method of producing artistic composite from artistic fabric by using silk fiber reinforced biodegradable plastic, which is designated as 'silk composite', for reinforcement. In order to expand applications of the silk composite, we performed the compression molding of decorative laminates with woody material, which was selected as a core material, and examined the properties of molded decorative laminates with various content of the silk composite. Since plywood and medium-density fiberboard (MDF) are widely used for decorative laminates, we selected them as core materials. As a result, flexible decorative laminates with high flexural strength were obtained by compounding the silk composite with wood materials.

This paper investigated the dyeability and surface color of silk and cotton fabrics dyed with chustnut bur extract. Some experiments were performed under the various dyeing conditions such as dyeing temperature, dyeing time, repetition of dyeing, dyeing pH, mordanting condition, washing fastness and light fastness with silk and cotton fabrics. The results obtained were as follows 1. △E value was increased when dyeing temperature and time was higher, value of munsell was shifted from Yellow to Yellow-Red at hither dyeing temperature and time in silk and cotton fabrics. 2. Optimal dyeing pH was increased with acidity of dyeing solution in silk and cotton fabrics, and repetition of dyeing did not change the dye-uptake. 3. When mordanting time and temperature was higher, △E value was larger in silk and cotton fabrics. Silk and cotton fabrics with Fe-premordanting treatment had best dyeability, but treatment with Sn-mordanting was worst. 4. Washing fastness and light fastness was excellent in various dyeing condition at silk fabric but cotton was without practical use.

In one bath dyeing system of silk/PET fiber blend fabric with acid/disperse dyes, adsorption behavior of disperse dyes and acid dyes on silk and PET fabrics were examined. In the dyeing of PET with C.I.Disperse Red 19(Red 19) and C.I.Disperse Red 60(Red 60) at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$, dye uptake with Red 60 was higher than that with Red 19. When the silk/PET dyed with Red 19 and Red 60 at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$, dye uptake on PET was influenced by affinity of the dye to the silk fabric dyed together. When the silk/PET dyed with Blue 80/Red 19 and Blue 80/Red 60 at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$ for 60 minutes, color of PET dyed with Red 19 and Red 60 was little influenced by Blue 80 but silk dyed with Blue 80 was influenced. Interrelation of K/S value and Munsell value was scarcely any but showed the change tendency of K/S value.

Dyeing properties of silk fabric with black tea colorants were investigated in terms of dye uptakes at various dyeing conditions and the effect of mordants on color change and colorfastness. Black tea colorants showed high affinity to silk and produced brown color. Two types of adsorption isotherm were obtained; Langmuir and Freundlich equilibrium at 360 nm and 460 nm, respectively. Thus, it is considered that both of ionic and hydrogen bondings are involved in silk dyeing with black tea colorants. Dye uptake increased continuously as concentration of colorants increased. Brown color was not changed with mordant type except that Fe mordant produced dark brown color. Mordanting did not influence colorfastness of dyed silk significantly. Therefore, mordanting was not necessary in dyeing silk with black tea colorants.
